OBJECTIVES Establishing similarities and differences between the performance of children from higher socioeconomic strata (4 and 5) attending kindergartens and those from low socioeconomic strata (1 and 2) concerning writing, notation, mode of production and style of speech. METHODS A set of initial and emergent writing assessment (IEWA) tasks were compared to evaluate three aspects of knowle...

We study geometric properties of linear strata of uni-singular curves. We resolve the singularities of closures of the strata and represent the resolutions as projective bundles. This enables us to study their geometry. In particular we calculate the Picard groups of the strata and the intersection rings of the closures of the strata. The rational equivalence classes of some geometric cycles on...

The relative reduction of risk for all-cause mortality among the elderly has been described as attenuated compared to younger subjects, but the risk for all-cause mortality increases with age when absolute risk is considered. The objectives of the present inquiry were to calculate the relative and absolute risks of all-cause mortality based on incidence rate ratios, and summarize these risks fo...
